Is there anything called business ethics? If you recalled our history thousands of years back, it's hard to have business ethics when you are in business. There would definitely be someone who will try and screw you up in the process in the effort to maximize their profit.

Several thousands of years later, some bright scholars wrote a book about business ethics - trying to change the mainstream of how business is done. If you are thinking of business ethics, it might not even exist - except for a minority group.
